摘要：

The photoluminescence of supramolecular assemblies of two lengthy oligothiophenes having eleven and seventeen repeat units that are end-substituted with third generation poly(benzyl ether) dendritic wedges, G3-T11-G3 and G3-T17-G3 respectively, is presented. Recent thermochromism studies revealed that these novel materials form nanoscale aggregates in solution. Variable temperature photoluminescence measurements confirm the complete transformation of a molecularly dissolved phase into an aggregated phase within a rather narrow temperature regime.
