Enhancement of the non-photochemical hole-burning efficiency of a silicon naphthalocyanine in the presence of electron acceptor activators

Micro- or nanorod and nanosphere structures derived from a series of phenyl-porphyrins

“…A considerable amount of research has been undertaken to advance the understanding of optical processes in low dimensional nanomaterials such as quantum dots, nanodisks, fullerenes and carbon nanotubes. [1][2][3][4][5][6][7][8][9][10] Self-assembled nano-and microstructured aggregates of p-conjugated molecules are of interest due to their structural similarities to photosynthetic antenna systems of green bacteria. [11][12][13] Such antenna systems channel the energy to the photosynthetic reaction center where light is converted into chemical energy via a charge separation process.…”

Persistent Spectral Hole Burning in Substituted Tetraazabacteriochlorin in Organic Polymer and Inorganic Silicate Xerogel

“…Free-base and metallo-naphthalocyanine derivatives in polymer hosts are examples of such materials. [6][7][8] Studies of PSHB in silicon-naphthalocyanine-doped polyvinylbutyral (PVB) with different additions showed that, in 2-color experiments, the holeburning efficiency can be increased, especially in the case of fullerene C 70 additive. 7,8 Recently, following the synthesis of unsubstituted tetraazachlorin, 9 more stable derivatives were synthesized that contain fragments attached to the reduced pyrrole ring which prevent its dehydrogenation.…”

Spectrally selective molecular doped solids: spectroscopy, photophysics and their application to ultrafast optical pulse processing

“…A chirp was introduced on one of the two pump pulses by a 1.7 cm thick plate of a SF58 glass and the spectral interference between the chirped and a reference unchirped pulse was engraved in the absorption band. Naphthalocyanine and naphthalocyanine derivatives based doped polymer and sol gel materials are promising for optical processing in the 800 nm range [25][26][27][28][29].…”
