Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

The First Zagreb Index, the Laplacian Spectral Radius, and Some Hamiltonian Properties of Graphs
MathematicsThe first Zagreb index of a graph G is defined as the sum of the squares of the degrees of all the vertices in G. The Laplacian spectral radius of a graph G is defined as the largest eigenvalue of the Laplacian matrix of the graph G.

Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Linear Maps Preserving the Spectral Radius
Journal of Functional Analysis, 1996 Let \(X\) be a complex Banach space and \({\mathcal B}(X)\) the algebra of all bounded linear operators on \(X\). For \(A\in{\mathcal B}(X)\) let \(\sigma(A)\) and \(r(A)\) denote the spectrum and the spectral radius of \(A\). It has been shown by \textit{A. A. Jafarian} and \textit{A. R. Sourour} [J. Funct. Anal.

On the maximum spectral radius of multipartite graphs
AKCE International Journal of Graphs and Combinatorics, 2020 Let be an integer. A graph is called r – partite if V admits a partition into r parts such that every edge has its ends in different parts. All of the r – partite graphs with given integer r consist of the class of multipartite graphs.
