Abstract
![]()
We present the synthesis,
photophysical properties, and biological
application of nontoxic 3-azo-conjugated BODIPY dyes as masked fluorescent
biosensors of hypoxia-like conditions. The synthetic methodology is
based on an operationally simple N=N bond-forming protocol,
followed by a Suzuki coupling, that allows for a direct access to
simple and underexplored 3-azo-substituted BODIPY. These dyes can
turn on their emission properties under both chemical and biological
reductive conditions, including bacterial and human azoreductases,
which trigger the azo bond cleavage, leading to fluorescent 3-amino-BODIPY.
We have also developed a practical enzymatic protocol, using an immobilized
bacterial azoreductase that allows for the evaluation of these azo-based
probes and can be used as a model for the less accessible and expensive
human reductase NQO1. Quantum mechanical calculations uncover the
restructuration of the topography of the S1 potential energy
surface following the reduction of the azo moiety and rationalize
the fluorescent quenching event through the mapping of an unprecedented
pathway. Fluorescent microscopy experiments show that these azos can
be used to visualize hypoxia-like conditions within living cells.

Abstract
A set of o-carborane-appended π-conjugated fluorophores and their light-emitting properties in the solid state are reported. The aggregation-induced emission enhancement (AIEE) exhibited for one of the fluorenyl derivatives paved the way to successfully preparing o-carborane-containing organic nanoparticles (NPs) homogeneously dispersed in aqueous media that maintain their luminescence properties. Notably, NPs processed as thin films also show high fluorescence efficiency, suggesting potential optical and optoelectronic applications.

Abstract
In this work we describe the ability of a simple enantiopure sulfoxide group to promote folding of oligo ortho-phenylene ethynylenes (o-OPEs) with one helical sense. A family of foldamers with up to seven triple bonds was synthesized and fully characterized. Moreover, changes in structure and chiroptical properties caused by Ag(i) coordination have been studied by NMR, UV, VCD and ECD measurements. Quantum mechanical DFT calculations support experimental results.

Abstract
The combination of photo-switchable units with macrocycles is a very interesting field in supramolecular chemistry. Here, we present the synthesis of a foldable container consisting of two different types of Lissoclinum macrocyclic peptides which are connected via two azobenzene units. The container is controllable by light: irradiation with UV light causes a switching process to the compact cis,cis-isomer, whereas by the use of visible light the stretched trans,trans-isomer is formed. By means of quantum chemical calculations and CD spectroscopy we could show that the trans→cis isomerization is spatially directed; that means that one of the two different macrocycles performs a definite clockwise rotation to the other, caused by irradiation with UV light. For the cis→trans isomerization counterclockwise rotations are found. Furthermore, quantum chemical calculations reveal that the energy of the cis,cis-isomer is only slightly higher than the energy of the cis,trans-isomer. This effect can be explained by the high dispersion energy in the compact cis,cis-isomer.

Abstract
Azobenzene and its derivatives are among the most commonly used switching units in organic chemistry. The switching process consists of two states, in which the trans isomer has a stretched and the cis isomer a compact form. Here, we have designed a system in which all isomeric states of an azobenzene moiety (trans → cis-(M) → cis-(P)) are passed step by step. The first step involves a change in the distance between the benzene units, which is common for azobenzene derivatives. In the second step an inversion of the helicity (M→P) of the cis azobenzene unit takes place. The third step leads back to the stretched trans isomer. This switching cycle is achieved by coupling the azobenzene unit with two chiral clamps and with a further azobenzene switching unit.
