“…The latter medium favored a higher iodine level (21.4 wt%) in the composite, and only within 1 h; the ambient conditions (298 K, 0.1 MPa) led to only 9.3 wt% and within 6 days. The conductivity of the I 2 composite was 1. porphyrin and polythiophene as a novel photoactive thin film (∼200 nm) was prepared by onestep electrochemical polymerization [388]. Iodine doping was done by dipping the composite polymer into acetonitrile solution of iodine for 5 min.…”

A unique feature of molecular iodine by far, is its ability to bind to polymeric materials. A plethora of natural and synthetic polymers develop complexes when treated with molecular iodine, or with a mixture of mole cular iodine and potassium iodide. Many unexpected findings have been encountered upon complexation of iodine and the polymer skeleton, including the color formation, the polymer morphology changes, the compl exation sites or regions, the biological activity, and the electrical conductivity enhancement of the complexes, with poly iodides (I n¯) , mainly I 3¯ and I 5¯, as the actual binding species. Natural polymers that afford such complexes with iodine species are starch (amylose and amylopectin), chitosan, glycogen, silk, wool, albumin, cellulose, xylan, and natural rubber; iodinestarch being the oldest iodinenatural polymer complex. By contrast, numerous synthetic polymers are prone to make com plexes, including poly(vinyl alcohol) (PVA), poly(vinyl pyrrolidone) (PVP), nylons, poly(Schiff base)s, poly aniline, unsaturated polyhydrocarbons (carbon nano tubes, fullerenes C 60 /C 70 , polyacetylene; iodinePVA being the oldest iodinesynthetic polymer complex.

“…However, the overall molecular set-up may be rearranged by either introducing axial ligands and/or other substituents attached to the carbon bridges (meso position) or replacing the hydrogens of the pyrrole units. Such modified porphyrin systems have shown a range of interesting physicochemical features, including photoactivity, optoelectronic and electrochemical properties, and hence they are supposed to find application in hi-tech materials [4][5][6][7][8][9][10][11], medical treatment [12][13][14][15][16][17], molecular recognition [18,19], photosensitizers and photocatalysts [20][21][22][23][24][25][26] as well as in different areas of modern technology.…”

“…Copolymerizations of bithiophene and porphyrin, bearing thiophene moiety, have been studied recently [31][32][33][34][35]. It was shown that electrochemically synthesized copolymer film of 5,10,15,20-tetra(3-hienyl)porphyrin (TThP) and bithiophene (BiTh) exhibited good efficiency for solar cell application [34].…”

As another derivate, the alkyl side chain length of alkylthiophene types also provide appropriate molecular structure as well as good electrical and optical properties for the compositions [36,37].…”
