“…3), the B(320∼400 nm) band and the Q (550∼800 nm) band, both correlate to π-π* transitions. The two bands are in agreement with the electronic spectrum characters of the metal phthalocyanines, 24 which further demonstrate that the structures of the M 2 Pc 2 C and M 2 Pc 2 HcC are accurate from the microscopic structure. The absorption intensity of M 2 Pc 2 C and M 2 Pc 2 HcC is relatively strong (shown Fig.…”

“…The two bands are in agreement with the electronic spectrum characters of the metal phthalocyanines, 28 which further demonstrate that the structures of the M 2 (PcTN) 2 O and M 2 (PcTA) 2 O are accurate from the microscopic structures. 36 To investigate the effects of peripheral substituents on the phthalocyanine ring, the absorption bands of M 2 (PcTN) 2 O and M 2 (PcTA) 2 O appear in the UV-vis spectra as shown in Fig. 4.…”

“…The two bands are the typical absorption bands of the metal phthalocyanines. 31 The Q band of b or b is einstein shift compared with that of corresponding a or a , which means that after the tetranitro in a or a reacted to become the tetraamino in b or b , the conjugation effect of b or b is enhanced. The results demonstrate that the structures of a, a , b, b are accurate from their microscopic structures.…”
