For Quenching Of 2C K(Q) Tau Is 157 M(-1) And For 3C,64 M(-1). When 1C Is Sensitized With Triplet Sensitizers Of Increasing E(T),N-Abstraction Increases (Table 1). These Data Indicate That N-And O-Abstraction In 1C Take Place From Distinguishable Triplet States. Survey Of Phi(P)'S Of Ring-Substituted Ketones 1B-D,6D,7A,B,D,8B,9B,D,10B,And 11D Demonstrates The Effect Of Substitution On The Competition Between N-And O-Abstraction (Table 2). For Methyl-And Diacyano-Substituted Ketones,The Results Can Be Understood Simply In Terms Of Shifts In E(T) Of The N Pi* And Pi Pi* States Of The Heterocycle. The Photochemistry Of All These Ketones Requires Consideration Of Interactions Among Three Triplet States. Doi:10.1021/jo00087A032

The present invention relates to dyes which are metal (M: Li, Na, K, Mg, Ca, Sr, Ba, Ti, Zr, V, Cr, Mo, Mn, Re, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, B, Al, Ga, In, Si, Ge, Sn, Pb, Sb, Bi, Se, Te) complexes of aromatic macrocyclic compounds of the type Phtalocyanine (Pc), Naphtalocyanine (Nc), Porphyrazine (Pz), Porphyrin (Pr), sub-Phtalocyanine (subPc), sub-Naphtalocyanine (subNc), sub-Porphyrazine (subPz), sub-Porphyrine (subPr), and relates to the synthesis of these complexes and derivatives. The subject matter dyes can be used in solar cell photovoltaic (PV) panels, in OLEDS which are organic structured light emitting diodes, in polymers, in textile and in photodynamic therapy PDT applications. Moreover, industrial applications are possible which depend on strong fluorescence characteristics.
