[摘要]:meso-Tris(oligo-2,5-thienylene)-substituted subporphyrins exhibit remarkably red-shifted and intensified absorption bands with increasing number of thienyl subunits. A dimeric subporphyrin obtained from homocoupling of a monobrominated tris(2-thienyl)-substituted subporphyrin exhibits a split Soret-like band due to the exciton coupling. |
