Abstract:
A chemical compound of the general formula: wherein:at least one of the W and W1 groups on a given phenyl ring is independently an electron-donating functionality and the other is independently selected from hydrogen and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving either Z or an adjacent substituent R; Z is either hydrogen or together with an adjacent substituent W or W1, forms a fused rigid ring as aforesaid; R1 and R2 are independently selected from hydrogen, a non-interfering chemical group, and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving an adjacent substituent W on the same phenyl ring; or together represent a first bridge joining the respective carbon atoms to which each R1 and R2 is attached, said first bridge being selected from direct bond and â€”(CH2)â€”; R3 is selected from hydrogen, a non-interfering chemical group and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving an adjacent substituent W1, or R3 forms a second bridge with R4, said bridge joining the respective carbon atoms to which each R3 and R4 is attached and said second bridge being selected from direct bond, â€”(C&boxH;O)â€”, â€”(CH2)â€” and â€”(CHOH)â€”; R4 is either hydrogen or together with R3, forms the aforesaid second bridge, with the proviso that R1 and R2 do not form a bridge when R3 and R4 form a bridge; R5 is either hydrogen or together with R6 forms a third bridge, said bridge joining the respective carbon atoms to which each R5 and R6 is attached and said third bridge being selected from â€”(C&boxH;O)â€”, â€”(CH2)â€” and â€”(CHOH)â€”; R6 is selected from hydrogen, a non-interfering chemical group and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving an adjacent substituent W1, or together with R5 forms the aforesaid third bridge; R7 is selected from hydrogen, a non-interfering chemical group and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving an adjacent substituent W1; R8 is selected from hydrogen, a non-interfering chemical group and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving an adjacent substituent W; and R9 is selected from hydrogen, a non-interfering chemical group and a bond of a fused rigid mono or polycyclic carbocyclic or N-heterocyclic ring involving an adjacent substituent W1.
