Growth And Optical Characterization Of Pts Polymer Single Crystals
Crystal growth; Nonlinear optics; Polymer crystal; PTS
The crystal growth technique and associated optical characterizations of polydiacetylene PTS, poly bis(p-toluene sulfonate) of 2,4-hexadiyne-l,6-diol, are reviewed in this paper. The commonly observed defects such as twinning and cracking and their origins are analyzed. Two factors were found to significantly decrease the density of defects and improve the quality. First, the monomer crystal was grown reasonably quick consistent with single crystal growth to reduce polymerization. Second, the polymerization rate was reduced dramatically for the 10% to 90% conversion region for a smooth conversion by reducing the polymerization temperature. The absorption spectrum, typical Z-scans for measuring the optical nonlinearity, and SEM pictures of the surfaces are given as measures of the optical quality of the PTS crystals.
