Non-covalent functionalization of single wall carbon nanotubes (SWCNTs) has been conducted using several binding agents with surface π-interaction forces in recent studies. Herein, we present the first example non-covalent sidewalls SWCNTs thienothiophene (TT) derivatives without requiring any agents. Synthesized TT derivatives, TT-CN-TPA, TT-CN-TPA2 and TT-COOH-TPA, were attached directly to through interactions obtain new TT-based SWCNT hybrids, HYBRID 1-3. Taking advantage presence sulfur...
Two carotenoids with aryl rings were studied by femtosecond transient absorption spectroscopy and theoretical computational methods, the results compared those obtained from their nonaryl counterpart, β-carotene. Although isorenieratene has more conjugated C═C bonds than β-carotene, its effective conjugation length, Neff, is shorter of This evidenced a longer S1 lifetime higher energy to values for On other hand, although renierapurpurin have same π-electron chain structure, Neff different...
Solution-processed organic photodiodes can function as thin-film candidates for solid-state photosensors in various optoelectronic applications due to the physical and chemical tuneability.
Excited-state properties of monomeric and aggregated carbonyl carotenoid 8'-apo-β-carotenal were studied by means femtosecond transient absorption spectroscopy. For monomers, the polarity-dependent behavior characteristic carotenoids with conjugated group was observed. In n-hexane S(1) lifetime is 25 ps, but it shortened to 8 ps in methanol. This shortening accompanied appearance new spectral bands spectrum. On basis analysis spectra methanol, we propose that polarity-induced are due...
In this study, subphthalocyanine–borondipyrromethene conjugates have been successfully designed and synthesized.
In order to estimate the possible structure of unknown carbonyl carotenoid related isofucoxanthin from Chromera velia denoted as isofucoxanthin-like (Ifx-l), we employed steady-state and ultrafast time-resolved spectroscopic techniques investigate properties Ifx-l in various solvents. The results were compared with those measured for carotenoids known structure: fucoxanthin (Fx) (Ifx). experimental data complemented by quantum chemistry calculations molecular modeling. show that must have...
We used ultrafast transient absorption spectroscopy to study excited-state dynamics of the keto-carotenoid fucoxanthin (Fx) and its two derivatives: 19′-butanoyloxyfucoxanthin (bFx) 19′-hexanoyloxyfucoxanthin (hFx). These derivatives occur in some light-harvesting systems photosynthetic microorganisms, their presence is typically related stress conditions. Even though hexanoyl (butanoyl) moiety not a part conjugated system hFx (bFx), spectra polar solvents exhibit more pronounced vibrational...
