Spiro-fused dibenzo[g,p]chrysene: annulative π-extension (APEX) synthesis and properties†
Employing spirophenanthrenes and phenanthrenone as template arenes for annulative π-extension (APEX), we synthesized a series of spiro-fused dibenzo[g,p]chrysenes (DBCs) in high yields. Experimental and theoretical investigations highlight the distinct advantages of spiro-DBCs, including characteristic fluorescence properties (412 nm) and enhanced thermal stability. This study provides insights into the electronic structure and potential applications of spiro-DBCs in organic functional materials.
