Organic porous polymer (OPP) materials are a class of multi-dimensional porous network materials

which are built via the strong covalent bonds linkage of various organic building blocks with different geometries and topologies

and recently become a new rising research field in porous material sciences.OPPs can be generally divided into two categories based on their degree of long-range order

including amorphous (e.g. CMPs

HCPs

PIMs

PAFs

etc.) and crystalline (e.g. COFs

CTFs) catalogues.Owning to their advantages of light-weight

large specific surface area

superior inherent porosity

excellent stability

pre-designable and precise tuneable structures and functions

OPPs have received increasing attention and research interests for their tremendous potential applications in gas storage/separation

heterogeneous catalysis

photoelectric conversion

chemical-and bio-sensing

energy storage and conversion

etc. We have developed a series of two dimensional (2D) and three dimensional (3D) functional organic porous network materials with excellent optoelectronic

or catalytic properties constructed by one or multiple organic conjugated building blocks owning specific functions

through self-polycondensation or copolymerization based on the so-called "bottom-up" strategy.In this article

we summarized recent examples reported by our group for the construction of multi-functional conjugated porous polymers of weaving organic conjugated functional molecules based on the bottom-up strategy

with a focus on the introduction of their structural features and exploration of their potential applications in photoelectric conversion and heterogeneous catalysis.Typical examples

of CMPs and COFs served as photodetectors

solid-state emitters

energy storage/conversion materials

and heterogeneous oxidation catalysts

were accordingly discussed.Some personal perspectives and challenges on the development of organic porous polymers were proposed in the last part of this article.Different from their counterparts (e.g. MOFs and zeolites)

OPPs own a much more bright future in photovoltaics and energy storage materials (e.g. supercapacitors and batteries) due to their superior stabilities and facile chemical post-functionalization.
