It seems to be a garbled or very professional chemical symbol expression. It is difficult to know what it refers to, so it is difficult to know its market price range. If you can explain the key information such as the characteristics and uses of this thing in clearer and more popular language, I may try my best to predict its market price range for you.

3,6-Bis (4-tert-butylphenyl) -2,5-diethynylbenzo [3,4-c] phenyne-1,4-dinitrile is a class of organic compounds with a special structure. Its stability is affected by many factors.
From the perspective of molecular structure, the benzene ring is connected to the alkynyl group, and the benzene ring has a certain conjugate stability, which can disperse the electron cloud, reduce the energy of the system, and make the molecule more stable. However, the existence of the alkynyl group brings certain instability factors. The carbon-carbon triple bond electron cloud of the alkynyl group has a high density, which is prone to reactions such as electrophilic addition, which reduces the stability.
In terms of steric hindrance, 4-tert-butylphenyl introduces a large steric hindrance, which can hinder other molecules from approaching, reduce the check point of reactivity, and have a positive effect on stability. In some environments, large steric hindrance groups can protect the central structure, reduce the reaction probability, and improve stability.
However, under certain conditions, such as high temperature, strong acid-base or strong oxidant environment, 3,6-bis (4-tert-butylphenyl) -2,5-diethynylbenzo [3,4-c] phenyne-1,4-dinitrile may change due to alkynyl reactivity, and the stability will decrease. For example, at high temperatures, the alkynyl group may undergo polymerization or react with other substances to change the molecular structure.
Overall, 3,6-bis (4-tert-butylphenyl) -2,5-diethynylbenzo [3,4-c] phenyne-1,4-dinitrile has certain stability under normal mild conditions, and the structure can be relatively stable due to the conjugation of benzene ring and steric resistance; however, under extreme conditions, due to the reactivity of alkynyl groups, the stability will be challenged.
