Chemistry
Over the past decade, CAS has worked hard to develop its research capacity
in chemistry. A group from USTC, following the demonstration of
single-molecule magnetism through molecular manipulation (13), succeeded
in integrating two functions into one molecule (14). In addition, through
resonant tuning of molecular states by nanocavity plasmons, they discovered
an unusual molecular electroluminescence at the nanoscale level (15).
These findings provide new insights into the functioning of single-molecule
devices and nanoscale optoelectronic integration.
At a supramolecular level, advances in understanding the driving forces
behind the formation of nanoarchitectures has enabled the rational design
of nano-patterned, hierarchical molecular assemblies, which have been
further used to investigate surface host-guest chemistry, surface chirality,
molecular electrochemistry, and other fundamental physiochemical properties
(16–18).
CAS scientists have made significant
progress in studying the catalytic performance
of dual catalysts (19) and in
understanding the interfacial confinement
(20) and morphological effects
(21) of some catalytic systems. CAS
chemists have also achieved a series of
breakthroughs in molecular electronics.
Synthesis and controllable assembly
of new conjugated molecular systems
(e.g., graphdiyne) have led to organic
semiconductors (p- and n-types) with
high mobility (>1.0 cm 2 .V -1 .S -1 ) (22, 23)
and photovoltaic materials with high en-
ergy conversion efficiency (>7.0%) (24,
25). Moreover, the interfacial properties
Hefei Synchrotron Light Source
within organic field-effect transistors have been investigated and new technologies
have been developed for low-cost, large-area, and flexible organic
circuits (26).
Nanoscience and Nanotechnology
CAS has pioneered and played a leading role in nanoscience research in
China. With its strategic deployment in the fields of nanomaterials, nanocharacterization,
nanodevices, and nanobiomedicine, CAS has achieved
significant progress in revealing fundamental aspects of the novel properties
of a wide range of engineered nanostructures. For examples, CAS
researchers have developed a series of nanostructures and multifunctional
nanodevices based on carbon nanotubes (27–30); graphene (31, 32);
graphdiyne (33); nanocrystalline copper with superplastic extensibility (34,
35), ultrahigh strength, and high electrical conductivity (36, 37); nanostructures
for high density memory devices (38) and high efficiency solar cells
(39); and drug delivery systems for cancer
therapies (40).
Significant progress has been made
in advancing technology transfer in the
energy, health, environmental, and manufacturing
sectors. A series of superhydrophobic
surfaces based on micro- and
nanostructures have been fabricated
(41, 42), leading to the invention of the
nanomaterial-based green printing plate
technology which has already been applied
successfully in the printing industry.

temperature vulcanization with silicone
