Z-shaped polycyclic aromatic hydrocarbons with embedded five-membered rings and their application in organic thin-film transistors
Z-shaped polycyclic hydrocarbons with embedded five-membered rings as well as their diaza-analogues have been synthesized and showed charge carrier mobilities up to 0.4 cm2 V−1 s−1 in organic p-channel thin-film transistors.
Restoring the pH-responsiveness for amine-conjugated 2-propionic-3-methylmaleic anhydride linkers
Azide-functionalized 2-propionic-3-methylmaleic anhydride linkers can conjugate amines, however, pH-resonsive reversibility can only be achieved for aliphatic primary amines by amidation in diethyl ether.
Two pyrene-based cagearene constitutional isomers: synthesis, separation, and host–guest chemistry
Herein we successfully synthesize two pyrene-based cagearene constitutional isomers and separate them to investigate their host–guest properties.

Pyridine-based tricarboxamides: complementary monomers for supramolecular copolymerization with C3-symmetric oligophenylenetricarboxamides
The formation of supramolecular copolymers between complementary chiral tricarboxamides 1 and 2 is investigated. The blocky microstructure of such heteropolymers has been elucidated by applying a co-assembly model. This model predicts the coexistence of large blocks of the homopolymers.
Quinoidal π-extension of dipyranylidene derivatives: towards efficient dopants for n-type organic semiconductors
Quinoidal π-extended dipyranylidene derivatives, 2,2′,6,6′-tetraphenyl-4,4′-(cyclohexa-1,4-diene-3,6-diylidene)dipyran (DP8) and its tetrakis(dimethylamino) derivative (DP9), were newly synthesized and characterized.
Selective deletion of one carbon atom from C60 through benzylamine mediated reactions
Benzylamine selectively adds to one of the two carbonyl groups on the 9-membered orifice to form an N,O-aminal moiety. Subsequent oxidation and hydrogen atom transfer lead to a decarboxylation process and formation of a nor [59]fullerene derivative.
Assembly of ionic supramolecular polymers using a decacationic pillar[5]arene to noncovalently crosslink hyaluronic acid for short DNA delivery
A multicationic pillar[5]arene noncovalently crosslinks hyaluronic acid to afford ionic supramolecular polymers for intramolecular delivery of short DNA.
Highly selective separation of toluene/methylcyclohexane based on pagoda[5]arene nonporous adaptive crystals
Herein the selective separation of toluene/methylcyclohexane based on pagoda[5]arene nonporous adaptive crystals is investigated.

Tetra-azobenzene extended calix[4]pyrroles: influence of photo-isomerization on chloride binding and its transport through liposomal membranes
Photo-modulation in chloride binding affinity and transmembrane transport with tetra-azobenzene extended calix[4]pyrroles.
About this collection
Organic Chemistry Frontiers is delighted to present this collection of articles dedicated to Professor Frank Würthner in celebration of his 60th birthday.
Frank Würthner, the chair professor of Organic Chemistry at the University of Würzburg, is a pioneer in the fields of organic dyes, supramolecular chemistry and materials. From 2015 to 2024, Frank served as the Associate Editor of Organic Chemistry Frontiers, making instrumental contributions to the rapid growth of the journal, particularly in his areas.
This themed collection, guest edited by Agnieszka Nowak-Król (University of Würzburg), Gustavo Fernandez (University of Münster) and Florian Beuerle (University of Tübingen), is a tribute to Frank’s outstanding career. It highlights recent significant advances in the broad field of organic chemistry, with a particular focus on functional organic molecules.
More articles will be added as soon as they are published.
