Abstract: This paper describes solution electronic spectral properties and solvatochromic behavior of polydiacetylenes obtained from the solid state polymerization of a series of asymmetric quinolyl substituted diacetylenes with (CH2)nnBCMU as the other substituent (where n = 2, 3, 4, and 9). The pristine polymers, upon dissolution in chloroform, exhibit blue shifted absorption. The addition of hexane to chloroform solutions of the polymers causes dramatic chromic changes and development of red shifted structured spectra. The spectral observations have been examined in terms of influence of substituents on the electronic absorption spectra.
