Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A new BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) was synthesized and investigated for photophysical and chemical properties based on donor-photoinduced electron transfer (d-PET) inhibition.Its sensing detection mechanism has been fluorescence turn-on involving d-PET blocking which was in-depth investigated by spectroscopy and electrochemistry, as well as by TD-DFT calculation.Strategically, d-PET was blocked by H-bonding from ethyl acetate and self-assembly of BDPPHOH via HO-and NO 2 -fragments in BDPPhOH.
