Abstract

In the interest of finding useful materials systems for optical limiting, we have sought to combine the attractive third order nonlinear optical properties of polydiacetylenes (PDA) with the desirable ballistic and mechanical properties of polycarbonates in our study of two different systems. Composites of Lexan polycarbonate with the PDA from 1,6-di-N-carbazolyl-2,4-hexadiyne have attractive laser power transmission characteristics. Macromonomers derived from the chloroformates of bis -phenols A and F and diacetylene diols were synthesized, their spectral, molecular weight, and thermal properties were studied, and the crosslinking of the macromonomers to PDA structures was investigated.
