"Pork is only 9 yuan / jin now, you can buy a little more for the New Year while the price is cheap. " At a large supermarket in Beijing's Chaoyang District, a salesperson told customers who came to buy New Year goods, "Compared with the most expensive time of 22 yuan per jin, the price is now more than half. " " We report the first realization of high thermal conductivity in the thin film of a conjugated polymer, poly (3-hexylthiophene), via bottom-up oxidative chemical vapor deposition (oCVD), taking advantage of both strong C=C covalent bonding along the extended polymer chain and strong π-π stacking noncovalent interactions between chains. RAFT polymerization is an ideal synthetic method for biomolecule-polymer conjugates because it is a robust and versatile process. 3 Radical polymerization processes are usually compatible with peptides or proteins since the propagating radical is non-reactive with the majority of functional groups associated with these biomolecules.

Conjugated polymers (CPs) with deep LUMO energy levels ( ELUMO s) are essential for developing n-type organic electronics. However, few approaches can markedly lower the ELUMO s of CPs. Herein, this issue is addressed by the introduction of a quinoidal building block into the polymer chain. This can be accomplished by rearranging the following formula for the observed mass of an n-mer in the mass spectrum (M n-mer ): M n-mer = n (M RU) + M EG1 + M EG2 + M ion where n = the degree of polymerization, M EG1 = mass of the α-end group, M EG2 = mass of the ω-end group, M RU = the mass of the repeat unit of the polymer Abstract.
