Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 121 words
A porphyrin derivative represented by general formula (I): wherein R 1 represents a lower alkyl group, -CH=CH 2 , -CH 2 CH 2 CO 2 H, a substituted or unsubstituted aryl group; h represents 0 to 8 wherein, when h is not smaller than 2, R 1 each may be the same or different; X represents or -CH 2 CH 2 -; m represents an integer of 2 to 4; n represents 0 to 4; Y represents -(CH 2 ) ℓ - or -CO-(CH 2 ) ℓ -CO- wherein ℓ represents an integer of 2 to 5; R 2 represents H or a lower alkyl group; and k represents an integer of 1 to 4, or a metal complex compound thereof.
Claim 2
Dependent Claim 121 words
A porphyrin derivative represented by general formula (I): wherein R 1 represents a lower alkyl group, -CH=CH 2 , -CH 2 CH 2 CO 2 H, a substituted or unsubstituted aryl group; h represents 0 to 8 wherein, when h is not smaller than 2, R 1 each may be the same or different; X represents or -CH 2 CH 2 -; m represents an integer of 2 to 4; n represents 0 to 4; Y represents -(CH 2 ) ℓ - or -CO-(CH 2 ) ℓ -CO- wherein ℓ represents an integer of 2 to 5; R 2 represents H or a lower alkyl group; and k represents an integer of 1 to 4, or a metal complex compound thereof.
