On applying pressure with a press in the solid state, the title compounds undergo homolysis of the central C–C bond to give green-colored radicals. X-Ray structure analysis for p-chloro derivative showed that the central C(2)–C(2′) bond was not

Anthracenes containing a chiral substituent at the 9-position, AnCH(OAc)R (An = 9-anthryl; R = Me, Et, i-Pr, t-Bu, CF3), dimerized on UV irradiation in benzene to give two head-to-tail dimers, meso- and dl- forms with 1:1 ratio. In the solid state, s

Complex formation of 7,7,8,8-Tetracyanoquinodimethane (TCNQ) with p-phenylenedimalononitrile (molr ratio 1 :2) was assumed by DSC and IR spectral measurements. The complex shows very sensitive chromic phenomena when it contacts with moist air or with

These compounds rapidly undergo photochemical cis-trans isomerization in solution, while irradiation of cis-(I) in the solid state almost exclusively afforded an intramolecular [4+2] cyclization product, suggesting that the isomerization would be inh
