Visible/Near-Infrared Porphyrin-Tape/C60 Organic Photodetectors
Porphyrin compounds are provided. The compounds may further comprise a fused polycyclic aromatic hydrocarbon or a fused heterocyclic aromatic. Fused polycyclic aromatic hydrocarbon s and fused heterocyclic aromatics may extend and broaden absorption, and modify the solubility, crystallinity, and film-forming properties of the porphyrin compounds. Additionally, devices comprising porphyrin compounds are also provided. The porphyrin compounds may be used in a donor/acceptor configuration with compounds, such as C 60 .
1 . A compound having the structure:
wherein R1-R24 are independently selected from the group consisting of hydrogen, hydroxyl, halogen, chalcogen, mercapto, alkyl, fluoroalkyl, alkoxy, amino, cyano, alkenyl, alkynyl, aryl, and heteroaryl;
wherein at least two of R1-R24 are each a fused polycyclic aromatic group or a fused heterocyclic aromatic group, wherein each fused polycyclic aromatic group and fused heterocyclic aromatic group are fused to the fused porphyrin of Formula I, wherein when the at least two R1-R24 are adjacent, the at least two R1-R24 correspond to the same fused polycyclic aromatic group or the fused heterocyclic aromatic group;
wherein M is a dicoordinate, tricoordinate, tetracoordinate, pentacoordinate or hexacoordinate metal ion or 2 hydrogen atoms; and
wherein n is 0-100.
