Abstract
Large polysilane spherulites have been observed. The spherulites were prepared by controlling the removal rate of solvents from poly(n-butyl -n-pentylsilane) under a xylene atmosphere. The diameter of the spheru lites was greater than 0.1 mm. The structure of the spherulites was co mpared with that of the polysilane powder by polarized microscopy, SEM , DSC, and x-ray diffractometry. A high photoluminescence quantum yiel d of 0.3 was obtained for the spherulites. (C) 1997 John Wiley & Sons, Inc.
