| Outline of Final Research Achievements |
In this research project, a series of novel near infrared (NIR) dye molecules based on large pi-scaffold expanded porphyrin possessing with multiple metal ion coordination sites were successfully synthesized and characterized. Providing a rational design for multi-functional dyes demonstrating intense absorption and emission in the NIR region should be attractive for various material applications such as bio-imaging etc. The direct core modification strategies of the macrocyclic chromophores and subsequent bis-metalation gave rise to the distinct pi-electron number-dependent features/properties attributed from the aromaticity-dependent structures. In this way, we have conducted systematic investigation on the structure-properties relationship of the expanded porphyrin-based NIR dyes.
