Construction of J- and H- Aggregates of meso-Tetrakis (4-hydroxyphenyl) porphyrin Diacid (H_4THPP^(2+))

摘要

UV-Vis spectrum was utilized to study the aggregation behaviors of H4THPP2+ inDMF-chloroform mixture and water. It was found that J-aggregation of H4THPP2+ was formed inDMF-chloroform mixture and H-aggregate was formed in aqueous solution with highionic-strength, as indicated by different spectral characteristics of different H4THPP2+ aggregates.
