If used in optical diodes (OLEDs), it can improve its optical efficiency and chromaticity, making the display a more realistic surface, and promote the development of optical properties.
Therefore, to promote the transformation of [1,5-a] to its-2-naphthalic acid with its characteristics, it plays an indispensable role in many important domains, and promotes the innovation of many technologies.

This is an organic compound whose physicochemical properties are particularly important and related to applications in many fields. Although "Tiangong Kaiwu" does not directly describe this object, the wisdom of the ancients in the exploration of the properties of chemical substances can be deduced slightly from relevant experience.
In terms of physical properties, the [1,5-a] and the - 2-naphthalenecarboxylic acid may have a specific form. At room temperature, it is either solid, looking at its appearance, or crystalline powder, with a certain luster. Its color may be almost colorless to slightly yellow, which has a specific performance on light absorption and reflection due to the characteristics of molecular structure. Its melting point is quite critical. It has been determined by modern research that it is about a certain temperature range. This temperature changes the intermolecular force and causes the substance to change from solid to liquid. And this substance has different solubility in common organic solvents. In some polar organic solvents such as ethanol and acetone, it may have a certain solubility. Due to the interaction between molecular polarity and solvents, but in non-polar solvents such as n-hexane, the solubility may be very low.
Discussing chemical properties, the carboxylic group is reactive to the [1,5-a] and its-2-naphthalene carboxylic acid. Carboxylic groups are acidic and can neutralize with bases to generate corresponding salts and water. For example, when reacted with sodium hydroxide to form sodium salts, this reaction reflects its acidic properties. And the carboxyl group can participate in the esterification reaction, and the alcohol is dehydrated under the action of a catalyst to form an ester compound. This reaction is commonly used in organic synthesis and can construct complex organic molecular structures. In addition, the naphthalene ring part of the molecule has certain stability. However, under specific conditions, such as the action of a strong oxidant or an oxidation reaction, the structure of the naphthalene ring may be destroyed, resulting in oxidation products and changes in chemical properties.

To prepare alkynes [1,5-a] alkynes and their 2-carboxylic acids, there are many methods for synthesizing them, and each has its advantages and disadvantages. The following are the main ones.
First, halogenated hydrocarbons are used as starting materials. The elimination reaction between halogenated hydrocarbons and strong bases in a suitable solvent can gradually build an alkyne skeleton. For example, by selecting a suitable dihalogenated hydrocarbon, first interacting with a strong base such as sodium alcohol, an elimination reaction occurs to form an olefin, and then again eliminating the formation of alkynes under stronger alkaline conditions or higher temperatures. Subsequently, by reacting alkynes with carbon dioxide under specific conditions, carboxyl groups can be introduced to produce the target 2-carboxylic acid. The raw materials of this method are relatively easy to obtain, and the reaction conditions are relatively conventional, but the steps are slightly complicated, and the reaction conditions of each step need to be carefully controlled to ensure the purity and yield of the product.
Second, the nucleophilic substitution reaction of alkynes is used. Select a suitable alkyne lithium reagent or alkyne magnesium reagent, and react with the corresponding haloalkane to directly generate the target alkyne structure. After that, the alkyne is carboxylated. For example, the alkyne is converted into an aldehyde by borohydrogenation-oxidation reaction, and then further oxidized to a carboxylic acid. This method is relatively direct, but the preparation of alkyne reagents requires harsh conditions such as anhydrous and anoxic conditions, and the stability of the reagents is not good, so the operation requirements are high
Third, the carbonyl compound is used as the starting material. For example, the condensation reaction of diethyl malonate with aldodes or ketones under basic conditions is used to construct an intermediate containing a specific structure, and then it is converted into alkynes through steps such as hydrolysis and decarboxylation. Subsequently, carboxyl groups are introduced through a series of oxidation or substitution reactions. This approach can cleverly utilize the reactivity of carbonyl compounds, but it involves multi-step reactions. The overall route is relatively complicated, and the reaction sequence and conditions are extremely controlled.
All these synthesis methods have their own strengths and weaknesses. In practical application, it is necessary to carefully select the optimal method according to the availability of raw materials, reaction conditions, cost considerations and product purity requirements, etc., in order to efficiently synthesize the required alkynes [1,5-a] and their -2-carboxylic acids.
