Advanced Science, EarlyView.We report a high‐dipole interlayer, MQPPO, that simultaneously improves efficiency and stability in perovskite solar cells. Its strong interfacial dipole enhances photovoltaic performance, while its uniform coverage and strong interaction with Ag effectively suppress AgI formation, ensuring long‐term stability under moisture and thermal stress.

A Direct Method for Synthesis of Quinoxalines and Quinazolinones Using Epoxides as Alkyl Precursor
Molecules, 2023 An iodine-mediated one-pot synthesis of pyrrolo/indolo [1,2-a]quinoxalines and quinazolin-4-one via utilizing epoxides as alkyl precursors under metal-free conditions has been described.

Advanced Science, EarlyView.A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

INVESTIGATION DICARBONYL COMPOUNDS GENERATED FROM THE MAILLARD REACTIONS OF METHIONINE WITH REDUCING SUGARS TO ENFOLD OFF FLAVOR IN GOAT’S MILK [PDF]
, 2016 Population of goat in Indonesia remains low and stagnant (about 1.2 % per year). In the other hand, Indonesia is a tropical country, which is suite for the goat’s growth. One of strong reason is low in goat-based product’s demand since “goaty” flavor

Synthetic strategies for 5- and 6-membered ring azaheterocycles facilitated by iminyl radicals [PDF]
, 2016 The author thanks EaStCHEM for financial support.The totality of chemical space is so immense that only a small fraction can ever be explored. Computational searching has indicated that bioactivity is associated with a comparatively small number of ring ...

Advanced Science, EarlyView.We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...

Quinoxaline chemistry. Part 8. 2-[anilino]-3- [carboxy]-6(7)-substituted quinoxalines as non classical antifolate agents. Synthesis and evaluation of in vitro anticancer, anti-HIV and antifungal activity [PDF]
, 1997 Thirty quinoxalines bearing a substituted anilino group on position 2, a carboethoxy or carboxy group on position 3 and a trifluoromethyl group on position 6 or 7 of the heterocycle were prepared in order to evaluate in vitro anticancer activity ...
