Journal ArticleDOI
Optically active single-walled carbon nanotubes.
Xiaobin Peng,Xiaobin Peng,Naoki Komatsu,Sumanta Bhattacharya,Sumanta Bhattacharya,Takanori Shimawaki,Takanori Shimawaki,Shuji Aonuma,Takahide Kimura,Atsuhiro Osuka +9 more
TL;DR: It is shown that optically active SWNT samples can be obtained by preferentially extracting either right- or left-handed SWNTs from a commercial sample, and diporphyrin molecules can be liberated from the complexes afterwards, to provide optically enrichedSWNTs.
Journal ArticleDOI
Tunable solvatochromic response of newly synthesized antioxidative naphthalimide derivatives: intramolecular charge transfer associated with hydrogen bonding effect.
Sayaree Dhar,Somnath Singha Roy,Dipak Kumar Rana,Sudin Bhattacharya,Sumanta Bhattacharya,Subhash Chandra Bhattacharya +5 more
TL;DR: The solvatochromic behavior of two newly synthesized naphthalimide derivatives (I and II) which have potential antioxidative activities in anticarcinogenic drug development treatment, has been monitored in protic and aprotic solvents of different polarity applying steady-state and time-resolved fluorescence techniques.
Journal ArticleDOI
Study of the formation equilibria of electron donor–acceptor complexes between [60]fullerene and methylbenzenes by absorption spectrometric method
TL;DR: The electron donor-acceptor (EDA) interaction between [60]fullerene and three methylbenzenes has been studied in carbon tetrachloride medium at a number of temperatures and it has been found that these methylbenzines form stable 1:1 EDA complexes with [60], which are more intense than usual in the 410-460 nm region.
Journal ArticleDOI
Study of ground state EDA complex formation between [70]fullerene and a series of polynuclear aromatic hydrocarbons
TL;DR: Ionisation potentials of the donors and CT transition energies have been found to correlate in accordance with Mulliken equation and from this correlation the electron affinity of C70 has be found to be 2.59 eV.
Journal ArticleDOI
Room temperature solution studies of complexation between o-chloranil and a series of anilines by spectrophotometric method
TL;DR: Electron donor-acceptor (EDA) complex formation between o-chloranil and a series of anilines and the charge transfer (CT) transition energies of the complexes are found to change systematically with change in the number and position of the methyl groups in the donor molecules (methylanilines).
