*G*is

*conflict-free connected*if every two of its vertices are connected by a path, which contains a color used on exactly one of its edges. The

*conflict-free connection number*of a connected graph

*G*, denoted by

**Front Cover**: In article number 1700871, Jianbo Tan, Li Zhang, and co‐workers describe a novel enzyme‐catalysis‐induced reversible addition‐fragmentation chain transfer (RAFT)‐mediated dispersion polymerization for preparing AB diblock copolymer nano‐objects with complex morphologies, performed at room temperature. Taking advantage of the oxygen‐tolerant feature of enzyme cascade catalysis, block copolymer...

*vertex-monochromatic path*if its internal vertices have the same color. A vertex-coloring of a graph is a

*monochromatic vertex-connection coloring*(

*MVC-coloring*for short), if there is a vertex-monochromatic path joining any two vertices in the graph. For a connected graph
