Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 110-52-1, is researched, Molecular C4H8Br2, about Ultrafast electronic dynamics and vibrational dynamics of SWCNT under alkylation and annealing, the main research direction is carbon nanotube alkylation annealing ultrafast electronic vibrational transient absorption.Reference of 1,4-Dibromobutane.
Using ultrashort visible pulse laser, the authors have performed transient absorption spectroscopy to study the electronic relaxation and vibrational dynamics for 3 single-wall C nanotube (SWCNT) samples of nonsubstituted SWCNT, alkylated SWCNT, and annealed alkylated SWCNT. Estimated lifetimes of ∼100 fs and ∼1 ps can be assigned to intraband and interband relaxation processes, resp. Compared with the nonsubstituted sample, the intraband transition rate is 7% smaller for the alkylated sample and nearly equal to the annealed alkylated sample within 2%. It implies that the intraband relaxation rate is not affected by alkylation itself but inhibited by excess chem. modification. Conversely, the interband relaxation rate shows no difference between the 3 samples. Short-time Fourier transform anal. of the measured traces of pump-probe delay dependent difference absorbance visualizes the change of mol. vibration frequency reflecting the energy transfer from (6,5)-SWCNT to (6,4)-SWCNT and the mol. structure change during the interband transition.
There is still a lot of research devoted to this compound(SMILES：BrCCCCBr)Reference of 1,4-Dibromobutane, and with the development of science, more effects of this compound(110-52-1) can be discovered.
