Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers
Chemistry – A European Journal, EarlyView.Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Donor−Acceptor 9-Uncapped Fluorenes and Fluorenones as Stable Blue Light Emitters,
, 2016 The “green emission defect” (GED) produced by fluorenones has significantly retarded the commercial scope of fluorene-based B-OLEDs. In this paper, for the first time, it is demonstrated that the “green light” emitting fluorenones 7 can be converted to ...

Bright Solvatochromic Fluorophores With Dual Emission Enabled by a Donor‐Engineering Strategy
Chemistry – A European Journal, EarlyView.We screened tertiary amines for installation on the donor unit of highly emissive donor–acceptor‐type solvatochromic fluorophores based on a 9,9‐dimethyl‐2‐phenyl‐9H‐fluorene scaffold, with the aim of enabling two bright emissive states to coexist. As a result, the azetidine derivative [4] and the azepane derivative [7] exhibited clear dual emission ...

Lysosome‐Targeted Squaramide Anion Transporters
Chemistry – A European Journal, EarlyView.Lysosome‐targeted squaramide anion transporters elicit different biological effects depending on the targeting group employed. ABSTRACT Targeting anion transporters to specific organelles has previously been shown to be an effective strategy to enhance their cytotoxicities against cancerous cell lines.

Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions
European Journal of Organic Chemistry, EarlyView.This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to
