In the first quarter of the twentieth century, one of the most significant events in physics and
chemistry was the establishment of the quantum theories of radiation, matter, and their …

A new series of nonplanar and unsymmetrically β-functionalized “push–pull” copper
corroles, CuTPC (CHO) R7 [R= H, Br, Ph, Me, or 2-thienyl (Th)], were synthesized and …

The use of conjugated organic compounds in fluorescence sensing applications has been
demonstrated to provide an impressive method to detect energetic nitro-aromatic …

Multiphoton absorption is of intense interest for a variety of potential applications, such as
optical power limiting, data storage, multiphoton microscopy, microfabrication, and …

Naphthobipyrrole-derived porphycenes are synthesized for the first time via McMurry
coupling of the β-alkylated 2, 9-diformylnaphthobipyrrole derivatives, which in turn were …

A novel linear multi-porphyrin array consisting of meso–meso coupled bis (imidazolyl-zinc-
porphyrin) was constructed by complementary coordination of imidazolyl to zinc. Although …

Two bridged-triphenylamine starburst molecules were designed and synthesized. Their
electrochemical properties were studied in detail using cyclic voltammetry (CV) and square …

We use wavelength tunable femtosecond pulses to measure intrinsic (simultaneous) two-
photon absorption (2PA) and three-photon absorption (3PA) molecular cross section in two …

Supramolecular porphyrin self-assemblies have been prepared from butadiyne-linked bis
(imidazolylporphyrin) by complementary coordination of imidazole to zinc, and their two …

The first theoretical prediction of a simultaneous two-photon absorption (TPA) event was
reported by Maria Göppert-Mayer in 1931 [1]. The development of high-energy pulsed lasers …
