“…Over the last two decades, there has been a continuing interest in the development of new optical limiters. − A good optical limiter must meet demanding specifications as the eye can be damaged by pulses of very low energy. As such, the device must be able to provide sensitive broadband response to long and short pulses and be resistant to laser-induced damage .…”

The nonlinear optical behavior of 2(3),9(10), 16(17),23(24)-tetrakis-(4aminophenoxy)phthalocyaninato indium(III) chloride (2) and its carbon nanotube composite in dimethylsulfoxide (DMSO) and dimethylformamide (DMF) solutions is described. The nonlinear third-order susceptibility and second-order hyperpolarizability values are also reported. A large nonlinear absorption that increased on covalent linking with single-walled carbon nanotubes (SWCNTs) was observed for the compound in DMSO. The nanosecond nonlinear absorption and the optical limiting behavior of this complex are shown to be dominated by a strong excited state absorption from a two-photon pumped state. The optical limiter using the new nanocomposite material (SWCNT-2) in the appropriate solvent showed a much lower threshold for optical limiting together with a much lower transmission at high fluences than previously reported nanocomposite limiters. The optical properties of the phthalocyanine and its conjugate were found to show high sensitivity toward the change of solvent matrix.

“…Photovoltaic (PV) devices based on semiconducting polymers have gained immense interests over the past few years [1][2][3][4][5][6][7], partly stimulated by the fact that the production process of the polymer-based PV cells is relatively simple, inexpensive and less polluting. In addition, by tailor-making some chemical structures of the polymeric materials, the flexibility and photoelectric properties of the materials can be tuned [8,9].…”

Fullerene functionalized polystyrene (PSFu) with a variety of fullerene (C 60 ) contents was synthesized and characterized. The best PSFu was selected on the basis of solubility and band gap energy for application studies. Feasibility for using PSFu as a replacement of C 60 in bulk heterojunction (BHJ) polymer solar cells was explored. Performance of the BHJ cells containing PSFu was comparable to that of the cells containing neat C 60 , irrespective of the acceptor=donor weight ratios, even the actual amount of C 60 in PSFu molecules was (about 5 times) lower than that of the neat C 60 .

“…In a typical polymer solar cell system, namely bulk heterojunction (BHJ), electron donor, and electron acceptor materials are blended together to form an active layer, which is then sandwiched between electrodes. Examples of such donor materials are semiconducting polymers that include poly(3-hexylthiophene) (P3HT), polyaniline, poly(p-phenylene-vinylene) (PPV), and its derivative, whereas those of the acceptor materials include graphene, fullerene (C 60 ), and its derivative phenyl-C 61 -butyric acid methyl ester (PCBM) [1][2][3][4][5][6][7][8][9][10][11]. Seeponkai et al [2] synthesized of C 60 functionalized polystyrene (PSFu) and explore a feasibility for using the PSFu as a replacement of C 60 in polymer solar cells.…”
